United Blood Services is organizing three blood drives in December in Carlsbad and are hoping to gain new donors.

Donor recruitment representative Stephanie Seabrease said majority of donors have regularly participated in the drive, but now they struggle to recruit new donors.

The drives attract 15 to 25 donors on average, Seabrease said.

"Five to 10 percent of the population is taking care of everybody," she said. "You never know, it could you or someone (who needs blood)."

Christmas is an essential time to donate blood, Seabrease said.

She said the holiday season is difficult to attract donors because families are on vacation.

"With the holidays coming up, there's a lot of accidents," she said. "We're not in critical shape but we definitely need our donors to come out. We always want to be prepared. It's a rough time of the year."
